/ was overflows

[三輪晋( Miwa Susumu )]

hi.

/ (root) was overflows.
How do I get to find out, consuming capacity?


question
========
I ran the sysbuild build. And it was in error.

/ was full for a long time. or impact of sysbuild. I do not know it.
As it, Where is / overflowing? I should I examine how?

You're looking at the wrong entry.

% df -h
Filesystem Size Used Avail %Cap Mounted on
/dev/wd0a 528M 527M -25M 105% /

You have 528M on the first partition and you've used it all.

I understanding of the mount seems to have missing.

thanks.

/ (root) was overflows.
How do I get to find out, consuming capacity?

i use the following or similiar for that job:

mkdir /mnt/root
mount /dev/volume-of-root /mnt/root
df -h /mnt/root/*

then if you found the file(s) which are so big, use i.e.:

lsof

or similiar tools to check who is writing/accessing that file.


hth
cheerioh,


Niels.

or similiar tools to check who is writing/accessing that file.

It is by dividing the mount point, and that isolate the problem.
In addition, I try to time it happens now.

thanks.

You need the -x flag to prevent du crossing mounts. What gives
du -m -x / | sort ...

I did not know -x options.

Hi

I've been using sysbuild twice a week as from Oct 5, 2013. You
might find both memory and disk usage is more than you expected.

Build pc, 3 GB ram, disk usage:
13G /home/sysbuild/nbsd-6_i386/i386
1.1G /home/sysbuild/nbsd-6_i386/release
1.5G /home/sysbuild/nbsd-6_i386/src
plus logs etc.

Trying to run a conf with 4 x ver + arch ran out of memory and
swap. Build of a single ver + arch doesn't touch swap.
